Lithium in Praesepe

Echelle observations are presented of lithium in 63 F and G dwarfs of the Praesepe cluster. For stars earlier than about G0V, Praesepe follows the same trends seen in the...本研究呈现了蜂巢星团（Praesepe Cluster）内63颗F型与G型矮星的锂元素阶梯光栅观测（Echelle observations）结果。对于光谱型早于约G0V的恒星，蜂巢星团的锂丰度趋势与……中所观测到的趋势保持一致。
